"next generation GPU interconnect for improved scaling"

Remember you still need a chip for the chips to communicate unless they were MCM, but even then (like Yorkfield/Kentsfield), there is a connect (otherwise the cores would never be able to communicate).

However, the sound of a next generation GPU interconnect is interesting... it looks like there IS indeed more than just CrossFire on the card as the 3870X2 which was just a bridge chip that simulated a PCI-E lane. The idea that there is an interconnect for communication might give credence to the cores themselves being tweaked to handle the interconnect.

Looks like R700 will score ~X7000 with a single R700... that's ridiculous considering the GTX280 scores what, just under 5K?

If you look at the cells and presentation panel by ATI @Cinama 2.0... it is very suggestive that the new HD 4000 series scales very well when adding a second card to the mix. Perhaps ATI is using a new "bus" of some sorts when multiple GPUs are being used!
